ABSTRACT:
In a continuously variable transmission with a pulley having discs (1, 2) wherebetween a driving belt (12) runs, at least one of the discs is movable for influencing the transmission ratio of the transmission. The moveable disc (1; 2) being mounted on a shaft (3), by support members (5; 7; 16, 18; 20, 21) possibly formed eccentrically relative to the shaft (3).
The support members take up the forces exerted by the driving belt (12) close to the point of application of the forces, so that in particular the movable pulley disc may be constructed less rigid, with a smaller mass and at a reduced cost price.
